KX-1840 COMMERCIAL CINEMA SURROUND 10m
Recommended maximum (array of 6 per side)
The KX-1840 is a compact cinema surround loudspeaker designed to be used where a high quality sound source is required and limited space is available. It features a 15 degree angled front baffle and an inverted driver configuration with the tweeter positioned under the bass driver. The combined high frequency response is exceptionally smooth and well controlled setting a new bench mark for surround loudspeaker reproduction. Typical applications include corner mounting in rooms with low ceilings or under balcony areas in cinemas where the projection box overhangs the seats at the back of the auditorium. Building on a long and successful history within the cinema industry, our in-house research, development and manufacturing team deliver a strong focus on quality and rigorous production standards. Every speaker that leaves Krix has been fully tested in an advanced acoustic measurement chamber. Tight production tolerances are upheld to ensure best-in-class product quality and reliability.
FEATURES •
Inverted configuration with high frequency driver facing downwards, ideal for corner mounting in architectural spaces.
•
High frequency drive unit with ferro fluid cooling, large roll surround, and doped fabric dome.
•
High power 6 ½ inch woofer with polypropylene cone and 33mm voice coil.
